AIM: To fi nd the current seroepidemiology of hepatitis A virus (HAV) in ***: A total of 2851 Kuwaitis applying for new jobs were ***: HAV-positive cases were 28.8%; 59% were males and 41% were females. The highest prevalence was in the Ahmadi area. High prevalence was among the group of non-educated rather than educated parents. This is the fi rst study in Kuwait demonstrating the shifting epidemiology of ***: This study reflects the need of the Kuwaiti population for an HAV vaccine.

Power requirements in the city of al Mirfa in western Abu Dhabi are covered by the al Mirfa Power and Distillation Plant. Comprehensive emission inventories for 2007-2008 were used to execute an ENVIMAN (OPSIS AB Company, Sweden) Gaussian dispersion model to predict ambient ground level concentrations of nitrogen oxides (NOx), carbon monoxide (CO), particulate matter (PM10) and sulfur dioxide (SO2) at selected receptors considering all emission sources located in the area. Two years of meteorological data was used in conjunction with the dispersion model to compute NOx and SO2 levels in and around the power plant. To validate the model, computed results were compared with the average values measured at a fixed Air Quality Station in al Mirfa city. The highest hourly, daily and annual ground level concentrations under exiting meteorological conditions were then analyzed. The computed results for the study area revealed that daily, hourly and annual concentration values did not exceed the Federal Environment Agency (FEA) standard, and the contribution of plant emissions to the ground levels pollutants in the surrounded area range from 3.1 to 109 μg/m3 for NO2, and 1.1 to 41.4 μg/m3 for CO. This study can be considered a baseline study for any future expansion in the plant. Based on these results, mitigation strategies are not required.

Hypocholesterolemic activity of Crataegus aronia L. (Rosaceae) is therapeutically praised. Its potent antiobesity (P < 0.001, n = 6 - 8) as well as marked triacylglycerol-reducing efficacies (P < 0.001, n = 6 - 8) in ... 详细信息

Hypocholesterolemic activity of Crataegus aronia L. (Rosaceae) is therapeutically praised. Its potent antiobesity (P al target for the management of dyslipidemia, atherosclerosis, diabetes and obesity. Comparable to acarbose, acute starch induced postprandial hyperglycaemia as well glycemic excursions in normoglycemic overnight fasting rats was highly significantly (P al hyperglycaemia increments, unlike diabetes pharmaco-therapeutics metformin and glipizide. C. aronia aerial parts as well as fruits AEs (0.1 - 10 mg/mL) were identified as in vitro dual inhibitors of α-amylase and α-glucosidase with respective IC50 (mg/mL) of 2.1 ± 0.3 and 3.5 ± 0.7. Still, it lacked on in vitro hindrance of glucose movement, dissimilar to guar gum. Equivalent to orlistat (PL IC50 of 0.1 ± 0.0 μg/mL), C. aronia tested AEs and its purified bioactive phytoconstituents;quercetin and rutin, inhibited highly substantially in a dose dependent trend PL in vitro (n = 3), in an ascending order of obtained PL-IC50 (μg/mL): quercetin;30.1 ± 2.8, rutin;77.3 ± 11.7, C. aronia aerial parts;225.2 ± 33.4 and C. aronia fruits;286.1 ± 37.4. Flavonoid-rich C. aronia, as a functional food and a nutraceutical, modulating gastrointestinal carbohydrate and lipid digestion and absorption, maybe be advocated as an exquisite and potential candidate for combinatorial obesity-diabetes prevention and phytotherapy.

We study types of boundedness of a semigroup on a Banach space in terms of the Cesáro-average and the behavior of the resolvent at the origin and also exhibit a characterization of type Hille-Yosida for the generators of ϕj-bounded strongly continuous semigroups. Furthermore, these results are used to investigate the effect of the Perturbation on the type of the growth of sequences.
